Specification of Letters Patent.

Patented Feb. 24, 1920.

Application filed August 24, 1916. Serial No. 116,676.

To all whom. it may concern.

Be it known that we, CHARLES M. BRAD- roan and RALPH C. SIMMONS,citizens of the United States, residing at Boston, in the county ofSuffolk and State of Massachusetts, and Beverly, in the county of Essexand $tate of Massachusetts, respectively, have invented certainImprovements in Shoe- Shaping Machines, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like has been inserted, it is the usual practice tosubject portions of the upper on the last to a beating operation inorder to eliminate wrinkles and cause the upper to conform closely tothe last. It is particularly desirable to treat in this manner the sidesof the upper, including the portions in and adj acent to thecreasebetween the upper and the sole, and also the top of the forepart of theupper. A practically unavoidable effect of the beating tool in thecrease adjacent to the sole, however, is the opening or widening of thecrease through the downward bendin of the projecting edge portion of thesole. For this as well as other reasons, therefore, it is desirable, forthe best results, to sub ect the sole as well as the upper to treatment,particularly the man ginal portion of the sole, in order to insure ashapely appearance in the finished shoe.

Important objects of this invention are to provide in a single machineimproved shoe shaping means in the use of which the shoe ma 'he readilymanipulated to secure the precise results required, and to provideimproved means for use in shaping both the upper and the sole of theshoe.

To the above and other ends, an important feature of the inventionconsists in a novel combination and arrangement of mechanism designed tofacilitate the presentation of a shoe to different tools in successionto cause the upper to be shaped in conformity to the last and to causethe sole to be operated upon to insure a close relation between theupper and the projecting edge portion of the sole and a shapelyappearance of the sole in the finished shoe.

ther features of the invention reside in novel means for operating uponthe upper of a shoe, including tools of a novel shape, and also a novelarrangement of the tool with reference to its operating means tofacilitate the effective treatment of the shoe.

We do not, however, claim in this application the sole shaping tool andits operating means per se, since that is claimed in the application forLetters Patent for an The above and other features of the invention,including certain details of .con-

struction and combinations of parts, will now be described withreference to the accompanying drawings and pointed out in the claims.

In the drawings:

The operative parts of the machine are mounted upon a frame 2 andinclude a main use of either tool at will without the necessity for anymaterial change of position on the part'of the operator. ii

nmeans such as that disclosed The tool 6 is arranged to be operated byin United {States Patent No. 768,560, granted upon the application of L.A. Casgrain on Aug. 23, 1190a, comprising an annular series of rolls llcarried by a drum 16 on the shaft 4 and arranged to impart downwardimpulses in rapid succession to a bar 18 which is slid- .ingly mountedfor vertical reciprocatory movement and to the lower end of which thetool 6 is secured. The bar 13 is arranged to 'be'pushed upwardly intothe path of the "rolls 16 by upward pressure of the work against thetool 6, and is normally maintained by gravity in its idle pos1t1on inI'which it is supported by the head of a stop -screw 20 in engagementwith a lug 22 on the side of the bar. Upward'pressure of a shoe againstthe tool 6 thus causes the tool to rece ve percusslonal impulses inrapid SLICCGSSIOIIIHS long as the shoe is pressed against it. the toolhaving substantially a beating effect upon the shoe, wherefore the tool6 is termed herein a beating tool.

By reference to Figs. 1 and 2 it will be seen that the tool 6, as hereinshown, comprises two portons or members 23 and 25, of which the member23 is shaped to operate upon the upper at the sides .of a shoe and themember 25 to treat the upper at the toe.- The side engaging member 23 ofthe tool is arranged to extend horizontally from side to side at thefront of tlie'machine and has opposite end portions substantiallyidentical in shape to permit opposite sides of a ment in the crease.

shoe to be presented alternately to the tool without the necessity ofreversing the shoe end for end.

In order that the member 23 may efi'ertively engage different portionsof an upper upon a last, its shoe engaging face presents a transverseconvex curvature, and

for the same purpose, as well as to facilitate engagement in the creasebetween the upper and the sole. the member 23 is also convexly curvedtransversely across each end, that is to say, the ends of member 23 areso shaped as to appear convex in a plan view. The member, moreover,tapers toward each end to a comparatively thin edge for engaget I Inorder that the tool may be used also for shaping the upper ence to Fig.2 it will be seen that the member 23 is inclined downwardly from frontto rear at an angle toits path of reciprocatory movement, thus causingits shoe engaging surface to face somewhat toward the front. One purposeand efiect of this arrangement is to render the manipulation of the shoeeasier for the operator, since, the

shoe be more conveniently presented to the tool and more easily heldagainst it with the necessary pressure if somewhat inclined from thefront downwardly than if held in a horizontal position while pressedupwardly and moved to bring different portions into engagement'with thetool. 7

The member 25 comprises a projection of the tool 6 somewhat above and atthe front of the member 23, and is shaped for engagement with the upperat the toe while the shoe. is held with the top of the forepart facingthe operator, the position of this member at the front of the tool beingsuch that the shoe may be more conveniently presented for treatment ofits toe portion, when required, than if the portion 23 were dependedupon to treat the toe as well as the sides of the shoe. In theconstruction shown in Figs. 1 and 2 the member 25 constitutes anintegral part of the tool 6, while' in the construction shown in Fig. 7which may be used as an alternative 7 construction, the member 25 isdetachable from other portions of the tool in order to permit it. to bereplaced or to be removed Where its use is not desired.

On most classes of work it is desirable to subject the upper to theinfluence of heat as well as to percussional impulses in order tofacilitate the shaping ofth'e upper to the last through the shrinkingaction of heat upon the leather. To this end the machine shown includesmeans for heating the tool 6 comprising a gas flame directed against thetool 3 from a burner'24l which is supplied with gas from a conduit 26,the flame being directed into a hollowed out portion on the rear side ofthe tool 6, shown by Fig. 2. The flow of gas and consequently the,degree of heat in the tool is regulated by a valve 27. The reciprocatorymovements of the tool, it. will be understood, are sufficiently shortftoinsure that the flame shall not be projected beyond the edges of thetoolinto engagement with the work. It will likewise be understood that thedisclosure of this particular heating means is merely illustrative andthat various means may be employed for heating the tool.

In order that the tool 6 may be maintained at such a temperature as toinsure effective results without becoming over-heated in such manner asto injure the work, it is desirable that means he provided forindicating con tinuously the temperature of the tool. To this end thetool is projected somewhat toward the front from the bar 18and is boredvertically at :28 to receive the bulb of a then mometer 30 which ismounted upon the front of the frame. VVhil-e the bore 28 is madesomewhat larger than the bulb in order to avoid breaking the bulb duringthe operation of the tool, and consequently the thermometer will notregister precisely the degree of heat in the tool, this difference willbe recognized as substantially constant, and with proper allowance forthe difference the temperature of the tool may be determined .w1thsufficient accuracy for practical purposes.

In connection particularly with the means for heating the tool, afurther important advantage attaches to the manner in which the tool ismounted, as hereinbefore described, with its upper engaging surfacedirected generally in inclined relation to its path of reciprocatorymovement. It will be evident that with the surface of the work presentedto the tool thus inclined to the direction of the beating impulse of thetool a slight relative slip between the tool and the shoe will takeplace at each impulse, the tool thus having an ironing efi'ect inaddition to its beating effect. Among other advantages this serves asinsurance against burning the leather by a dwell of the heated tool toolong in contact with the same portion of the surface.

Figs. 8 and 9 show an alternative form of upper beating tool 6 which issecured to a vertically reciprocatory bar 18 similar to the bar 18 ofFigs. 2 and 4:. The tool 6, when used, should preferably extend in substantially the same relation to the machine as the tool 6 in Figs. 1 and2, and as shown in Fig. 9 this tool has a lower surface curvedtransversely for engagement with the shoe, the tool being extended, asshown in Fig. 8, to permit it to be used for shaping portions such asthe top of the forepart of the upper and having an end portion taperingtoward its outer extremity and presenting a lower surface convexlycurved in different directions in order to facilitate ei'igagenient ofthe tool with the upper in the shank and close to the sole. The tool 6,moreover, has at its inner end a portion 31 shaped especially forengagement with the upper in the crease adjacent to the sole. The toolin the construction shown is arranged to be heated by a gas flameissuing from a stationary burner 24, thetoolbein g bored longitudinallyto receive the flame and having openings 33 for the escape of theproducts of combustion. In order to facilitate the heating of the outerend portion of the tool, the tool is inclined upwardly as shown in Fig.8.

The sole shaping tool 10 is carried by one arm 32 of a bell crank leverwhich is mounted on a rock shaft 34, the other arm 36 of the bell crankextending rearwardly toward the end of the shaft 8. The arm 36 is forkedat its rear end, and clamped to the forked portion is a rod 38 uponwhich a block 40 is slidingly mounted. The shaft 8 is provided at itsfront end with a crank disk 42 which carries a crank pin 4 L, theprojecting end of the pin n being j ournaled 1n the block 40. The pin L4is mounted on an eccentric 456 which is adjustable in the disk 42 tovary the eccentricity or throw of the crank pin and is secured inadjusted po sition by means of a bolt 48. Through these connections thebell crank 32, 36 and the tool 10 will be rapidly oscillated in acontinuous manner toward and from the operator during the operation ofthe machine.

It will be observed that the arm 32 is normally inclined forwardly fromthe vertical and consequently determines a path of movement of the tool10 which is inclined downwardly from front to rear, this incline beingsubstantially or approximately the same as the inclination of theportion 2-3 of the tool 6. The purpose and effect of this arrangement isto facilitate the presentation of the shoe to the tool 10 insubstantially the same manner as previously explained with reference tothe tool 6, it being much easier for the operator to press the shoediagonally upward and backward than directly upward against the tool.Since the tool 10 extends transversely at the front of the machine, insubstantially the same relation to the machine as. the member 23, theshoe may be presented to this member and to the tool 10 successivelywithout any substantial change in the lengthwise inclination of theshoe. In the construction shown the tool 10 is shaped to rub the sole,but it should be understood that in its broader aspects the invention isnot limited to a rubbing tool. The longitudinal concave curvature of theshoe engaging surface of the tool 10, as well as its transverse convexcurvature, as shown, facilitates the engagement of the tool with allportions of the sole which it may be de sired to treat and renders thetool particularly effective for shaping the marginal portion of thesole.

In the operation of the machine on some classes of work, such, forexample, as shoes made of patent or enameled leather, it is desirable,in order additionally to insure against burning the leather by contactwith the heated tool 6,.to apply a small quantity of oil orgrease to thesurface under treatment. The machine 7 is accordingly provided withgrease dispensing means comprising a. receptacle 50 mounted upon abracket 52 on the frame in convenient position for use and having anoutlet opening .in its bottom portion normally closed by a valve 54which rests upon a beveled seat on the receptacle and is maintainednorwardly from this recess on opposite sides of the stem are fluidconducting grooves which terminate at the lower end of the stem. hen thevalve is momentarily lifted, therefore, a small quantity of the fluidwill be admitted to the recess 58 whence it will run down the grooves 60to the lower end of the valve and hang suspended in drops forapplication to the work when the-work is presented inengagement with theend of the stem. It will be evident that the flow of the fluid down thegrooves 60 will continue after the valve has closed. In order tolocalize and hold the drops of fluid for application to the work, theend of the stem 56 is provided with depending projections 62 in linewith the grooves 60.

.The grease in the receptacle 50 is maintained in a fluid condition tocause it to flow readily by means of heat applied to the receptacle by agas burner 64.

In the operation of the machine the heated tool 6 will first be used,the shoe being pressed upwardly against the tool to cause the tool toreceive percussional impulses.

from its operating means. For the treatment of the side of the shoeclose to the sole the shoe will be positioned to cause an end of theportion 23 of the tool to project into the crease between the upper andthe sole and will be moved longitudinally to cause the tool to engagedifferent portions of the upper. If application of grease to the work isdesirable, this may be effected by engagement of the shoe with the stem56 of the valve 541. Afterjone side of the shoe has been'treated theshoe will usually be turned about its longitudi- 'nal and the other side1 resented to the opposite end of the tool, although the shoe may, ifpreferred, be turned end for end and the other side presented tothe-same end of the tool. If desired also other portions of the upper,such as the top of the forepart, may be shaped by engagement with thetool 6, preferably on the concave intermediate portion of the member 23;and if .the condition of the shoe requires the shaping of portions ofthe upper about the toe the ShOe may be presented to the member as shownin Fig. although this op,-

of the sole and press the edges toward the upper in such manner as toinsure a' close crease in case the edges may have been bent away from.the upper in the preceding upper shaping operation. Y

In the use of the alternativeform of tool shown in Fig. 8 both sides ofthe shoe are presented to the same end portion of the tool, the shoebeing turned end for end, and the member 31 is also used for shapingtheupper in the crease at both sides of the shoe as Well as around thetoe. The top of the forepart of the upper also may be shaped byengagement with the extended intermediate por'ion of the tool,

It will be evident from aconsideration of the foregoing disclosure thatthis'i'nvention provides a. machine which is especially useful in theproduction of a high grade and maximum quantity of Work, particularly byreason of its adaptability to the varying shapes of different styles andsizes of shoes, the facility with Whichthe work jmay be manipulated tocause the tool to engage all portions which require treatment and inpresenting the work to different tools in succession, and the ease withwhich the operation of the machine upon the work may be observed,

It will be, apparent also that the rapid reciprocating movement of thetool, as well as the relative slip between the tool and the shoe, willtend to obviate any burning of the leather by itscontact with the heatedupper engaging tool, since a dwell of the tool upon any portion of thesurface for such alength of time as to burn the material is thusavoided.
